cherry

n.

c.1300, earlier in surname Chyrimuth (1266, literally "Cherry-mouth"); from Anglo-French cherise, from Old North French cherise (Old French, Modern French cerise, 12c.), from Vulgar Latin *ceresia, from late Greek kerasian "cherry," from Greek kerasos "cherry tree," possibly from a language of Asia Minor. Mistaken in Middle English for a plural and stripped of its -s (cf. pea).

Old English had ciris "cherry" from a West Germanic borrowing of the Vulgar Latin word (cf. German Kirsch), but it died out after the Norman invasion and was replaced by the French word. Meaning "maidenhead, virginity" is from 1889, U.S. slang, from supposed resemblance to the hymen, but perhaps also from the long-time use of cherries as a symbol of the fleeting quality of life's pleasures.
